Totally worth the money!
The x0's cost was about $100 more than the x9, but the performance enhancement makes it soooooo worth it. I highly reccomend it. I previously had a x7 and the cage snapped off just from doing a bunny hop (weird right?). Anyways, make sure you follow the directions word for word when u install it, following all the torque specs. It will save you heartache later on.

Excellent, Fluid shifting
I have bought 3 of these for all my bikes now. They are great in all conditions. The open design is easy to clean and see the machanics for adjustments. I am using in 1x9 configurations and have no problems hitting any combination.

PROS: Easy Maintenance

CONS: Works best w X0 shifters

technical riding
Switched my Specialized Rockhopper from a triple to a single and needed a shorter derailleur, for better shifting and avoiding rock damage.
Works perfectly.

Great derailleur
This is a very nice derailleur. It shifts great and looks like a piece of art. It was a big step up from X7, I've heard X9 works as well, but if you have the cash this is worth it for the extra bling.

Wow
Wow. An engineering marvel on the tail of my bike. Bulletproof shifting coupled with graceful lines of metal and carbon that just LOOK beautiful. I recommend it wholeheartedly.
